Fig. 1 is the embodiment of the invention 1 structural representation;
Fig. 2 is the embodiment of the invention 2 structural representations.
The specific embodiment
With reference to shown in Figure 1, a kind of survival capsule and refuge chamber phase transformation heat sink mainly comprise survival capsule or refuge chamber 1, phase-change material 2, container or carriage 3, temperature control meter 4 etc.; Survival capsule or refuge chamber 1 inner bottom part or and the side or and the top or and unsettled container or the carriage 3 of being provided with, carriage 3 is at least one deck, it is provided with phase-change material 2, phase-change material 2 also can be arranged in the interlayer of survival capsule or refuge chamber 1; Be provided with temperature control meter 4 in survival capsule or the refuge chamber 1.
Described phase-change material 2 is selected the prior art commercially available prod for use, can be pure material or the mixture or the composite phase-change material of organic matter or inorganic matter or organic matter and inorganic matter, comprise and being not limited to: paraffin, the tetradecane, pentadecane, hexadecane, the tetradecane and hexadecane and inorganic salts, inorganic salt solution, the inorganic salts saturated aqueous solution, the pure substance of inorganic salts supersaturated aqueous solution or binary mixture or multicomponent mixture.
Organic matter can be a paraffin, binary mixture can be that the mass content of hexadecane was at 50～90% o'clock the tetradecane and hexadecane, used inorganic salts, inorganic salt solution, the inorganic salts saturated aqueous solution, the pure substance of inorganic salts supersaturated aqueous solution or binary mixture or multicomponent mixture comprise zinc nitrate hexahydrate, six hydration calcium chloride, Sodium acetate trihydrate, Disodium sulfate decahydrate, sal soda, disodium hydrogen phosphate dodecahydrate, ten hydration disodium tetraborates, potassium nitrate, the salt or the aqueous solution of aqueous sodium persulfate solution and Disodium sulfate decahydrate mixture etc.; Used nucleator comprises kaolin, graphite powder, and light metal powder such as aluminium; The adding nucleator also stirs, nucleator and inorganic salts, and inorganic salt solution, inorganic salts saturated aqueous solution, the percentage by weight of inorganic salts supersaturated aqueous solution are 0.1～20%.
With reference to shown in Figure 2, when the Minepit environment temperature is higher than the phase transition temperature of phase-change material, in survival capsule or refuge chamber 1 outside or inside prior art refrigeration machine 5 is installed, be communicated in survival capsule or the refuge chamber 1 by associated pipe, with the refrigerant of refrigeration or by the medium after the interchange of heat, the phase-change material that the cooling survival capsule is interior or refuge chamber is interior makes phase-change material be in the B phase.
Operating principle of the present invention: phase-change material has the characteristic of phase transformation cooling, A phase
Heat release → ← heat absorptionThe B phase is put into survival capsule or refuge chamber 1 with phase-change material 2, and the phase transition temperature of this phase-change material 2 is lower than the highest goal temperature of cooling area limiting, when the Minepit environment temperature is lower than phase transition temperature, only need put into the phase-change material 2 of B phase; When the Minepit environment temperature is higher than the phase transition temperature of phase-change material 2, give the phase-change material in the survival capsule or in the refuge chamber 12 coolings, make phase-change material 2 be in the B phase by the refrigerant of refrigeration machine 5 refrigeration or by the medium after the interchange of heat.
When mine accident or disaster take place, when needing to use survival capsule or refuge chamber 1, cut off refrigeration machine 5 power supplys, mine personnel enters survival capsule or refuge chamber 1, temperature raises in survival capsule or the refuge chamber 1 because heat that human body produces or the extraneous heat that produces make, when temperature rose to the phase transition temperature of phase-change material 2, phase-change material 2 absorbed heat, is the A phase by the B inversion of phases.When phase-change material 2 decalescences, temperature remains on the phase transition temperature constant in survival capsule or the refuge chamber 1.Have only the phase-change material 2 of working as all to be converted into the A phase time, survival capsule or refuge chamber 1 temperature just can continue to rise, therefore do not rise for maintaining the temperature in the certain hour, then place the B phase phase-change material of q.s in survival capsule or refuge chamber 1, promptly B phase phase-change material 2 is converted into the calorific value of A phase time heat absorption value greater than all generations such as personnel, equipment and environment in survival capsule or the refuge chamber.
For example: for making survival capsule or refuge chamber 1 in use, temperature is not higher than 35 ℃ in 4 days, should select for use phase transition temperature less than 35 ℃ phase-change material, for example uses Disodium sulfate decahydrate, and the phase transition temperature of Disodium sulfate decahydrate is 32.4 ℃, i.e. Na
2SO
4+ 10H
2O (A phase)
32.4 ℃ heat release → ← 32.4 ℃ of heat absorptionsNa
2SO
4+ 10H
2O (B phase), be lower than 32.4 ℃ as environment temperature in the mine, then Disodium sulfate decahydrate is in the B phase always, is higher than 32.4 ℃ as environment temperature in the mine and then need adopts refrigeration machine 5, refrigerant or by below the medium after the interchange of heat cooling Disodium sulfate decahydrate to 32.4 ℃ makes Disodium sulfate decahydrate be in the B phase.When mine accident or disaster take place when, refrigeration machine 5 deenergizations, the personnel in the pit enters survival capsule or refuge chamber 1, temperature begins to rise in survival capsule or the refuge chamber 1, when temperature rises to 32.2 ℃, Disodium sulfate decahydrate begins the phase transformation of absorbing heat, by the B inversion of phases is the A phase, according to the design number of users of survival capsule and refuge chamber 1 and the heat of relevant environment equipment generation, if total heat energy is produced as the N kJ (kilojoule) in 4 days, heat absorption is greater than the B phase of N kJ (kilojoule) when then only needing to place phase transformation survival capsule or refuge chamber 1 in, and Disodium sulfate decahydrate just can keep in 4 days survival capsule or refuge chamber 1 interior temperature not to be higher than 32.2 ℃.
